Abstract

An elevator features that its draw gear and counterweight are installed to the same side of its cage, so possessing less height (about the height of cage). The mechanism above the cage is very simple (only pulley holder and pulley), so it is unnecessary to build a machine room on roof. In the cage, there is a manual lifting mechanism for dealing with acciderts or power cut.

Description

The elevator of traction engine installed inside

Invention relates to the structure of elevator, and is special especially with towing machine and the counterweight pendulum structure in the same side of car.

Existing friction-driven formula elevator, its actuating device---towing machine all is contained in the top of elevator, generally all establishes machine room.This machine room has just accounted for the certain height space, in high building, the height space abundance, but in the lowrise, especially therefore private residence inner height space preciousness, is wished to adorn elevator and is not established machine room, and wish that car can be raised to the flooring of top layer---flat bed, some user for build machine room, elevator does not want to take the trouble.Machine room on the roof diminishes the outward appearance of building in addition.

Promote with winch, only need establish two pulleys at well headroom, take height space amount little (about 0.3 meter), just can not establish the top machine room, car reaches the top layer flooring---the requirement of flat bed.But winch promotes type of drive and friction driving way compares, and obviously is to have fallen behind.Some up-to-date technology, though can reach requirement as the linear motor driving mode, be that simple problem is complicated, and price height, below six floors highly every more than 90,000 dollars, rich Japanese family also seldom can bear.

The purpose of this invention is to provide a kind of little friction-driven formula elevator structure of height space that takies, need not establish machine room

Technical scheme of the present invention is: to containing the elevator of car, counterweight, towing machine, guide rail, traction steel-cable, towing machine and counterweight are contained in the same side of car, make the below operation of drawing machine to focusing on.Promote the hoist ropes of car, the deflection sheave of upwards being walked around the top by electric car is downward, links counterweight after passing towing machine.In the towing machine inside of side dress the device that prevents that car from sliding and falling is arranged, on car, is provided with the device of hand-operated lifting car, during in order to power failure in service or fault car be parked in two-layer between, the passenger can arrive with manual hoisting device close on the level flooring.Manual hoisting device is made up of retarder, rope sheave, handwheel, pulley, support and transmission shaft.Utilize the support of manual hoisting device, increase spring pressure regulating device and travel switch, formed the car load limitation device.

The advantage of such scheme: above cage operation, have only beam and deflection sheave, their shared height space are only about 0.3 meter, reach under the condition of not establishing machine room car can with top layer flooring flat bed, and be the friction-driven formula; Towing machine and counterweight are contained in the same side of car, and car guide rail and counterweight guide rail have been saved the taking of space almost in same plane, and car can open the door by three faces, for the user provides selection; Because towing machine self has the anti-car function of falling of sliding, and needn't establish safety tongs, thereby moment taking place not weigh needn't consider fall arrest stop car the time, has increased elevator alerting ability and variety.

Contrast description of drawings a kind of embodiment of the present invention below:

Two deflection sheavies [1] at top are contained on the back timber [2].This back timber is through in the wall hole under the smallpox, and also the form that can adopt a choicest to go out can also be contained on the guide rail bracket.Towing machine [3] is contained in the side of car [4].It in the dot-dash wire frame a kind of fall towing machine of function of anti-car that has, there is a drive wheel [5] inside, the race that many driving hoist ropes are arranged on its wheel rim, side controlled empty do to have an internally toothed annulus [6], gear [7] and internal gearing on the output shaft of retarder [8].In-to-in in addition two wheels is flower wheel [9,10], and the race on their wheel rim is identical with quantity on the drive wheel, and flute profile is also identical, and circle of projection also on their wheel rim, has made ratchet, has joined braking ratchet [11] near it.Hoist ropes [12] gets off to enter towing machine [3] around the pulley [1] at top, walks around a flower wheel [11] back and transfers to stretch out behind second flower wheel [10] around drive wheel [5] again, links counterweight [13].Drive wheel rotates, and makes the car lifting, skids (friction force deficiency) in the race of generation hoist ropes at drive wheel, and when quickening, control mechanism makes the using pawl to brake flower wheel, and hoist ropes obtains the friction force of stop car in the race of flower wheel.

The fixing means of towing machine [3]: go up welding two channel-section steels [18] at back timber [2], between distance identical with towing machine outside dimension (thickness), does two pitch-rows and the identical hole of towing machine mounting hole distance, get final product with the pin insertion.Towing machine also can be adorned by seat, and its method is to make 0.5 * 0.5m on the wall ²The hole, remake a permanent seat and get final product.

The hoist ropes [12] that links car [4] upwards behind two deflection sheavies of pile warp [1], enters towing machine [3] downwards, links counterweight [13] downwards.Gear on the motor reducer output shaft [6] band drive wheel [5] rotates, the i.e. edge guide rail operation separately of car and counterweight.

Car guide rail [15] and counterweight guide rail [16], almost in a plane, their available attaching partss are fixed on the wall or are fixed on the guide rail bracket.Do like this and can be the open the door selection of three faces of car.Car guide rail also can be symmetrical in car and install, and just because of without the safety tongs fall arrest, can not produce the out-of-balance force distance during stop car, and therefore symmetry is installed unnecessary.

Manual hoisting device on the car: after hoist ropes [12] is walked around pulley [17], link and be coiled on the rope sheave [18] fixing turn (length).Rope sheave [18] combines with worm gear [19], and worm screw [20] is rotated, and drive worm gear, rope sheave one run up, and rope sheave is received (or putting) hoist ropes, makes the car lifting, reaches and closes on flooring.The rotation of worm screw is to be rotated by the handwheel [21] that is located in the car, through a secondary umbrella tooth [22,23] and transmission shaft [24] realization.

One countershaft frame [2A] is arranged on the car, and rope sheave [18], worm gear [19] are between this countershaft frame, and be porose on the head outside two fork shaft framves of weighing bar [25], passes with same axis.Hole above-below direction on another countershaft frame [26] is long partially, and an axle passes the hole at weighing bar [25] middle part, the hollow of the hole of pedestal [26] and pulley [17].Porose on the flat board of the other end of weighing bar [25], a bolt [27] that is hinged on the car roof passes from this hole, and cover stage clip [28] is with spring perch nut [29] settling pressure, be transferred to when overloading to certain value, pulley [25] by the heavy bar of axle belt scale in its hollow is to rising.The amount of its rising is limited by the long partially up and down hole on the pedestal [26], presents in an amount at least sufficient to make a travel switch job (outage is shut down).

Establish the transverse distribution mechanism of hoist ropes tension force on the counterweight.Loaded van [13] center of top is being established one pair of pedestal [30], several single groove pulleys [31] are contained on the pedestal, about hoist ropes is divided into two groups, be connected with steel wire rope head [32] from left and right these pulleys of walking around respectively, after hitch rod [33] passes plate washer [34] hole, sleeve spring [35] distributes tension force with nut [36] to hoist ropes.
